Abstract

A device and method for data transmission between a transducer and a processing unit which are coupled by one or several signal transmission lines, to selectively activate at least two different modes of operation of the transducer. The device includes a comparator unit which identifies the respectively activated mode of operation by comparing signals present on at least one signal transmission line with predetermined reference signals.
